Thank you!
Couple more questions.
We are using Ardupilot / Ardurover and Mission Planner a described here: ArduPilot Integration | RTK Modules
How to validate that RTK data is being received by Pixhawk? Any value - like GPS2 in real time logs?
When setting up rover unit and base station unit - what are settings of tab “Base mode” should be - ON or OFF? As well on base station - should tabs “position input” and “correction output” should be switched to OFF?
